MD&A provides comprehensive refurbishment & repair of large utility turbine generator stators and fields, including high voltage bushing refurbishment and replacement and the complete rewinding of inner liquid-cooled generators.
Our turbine-generator repair facility centrally located in St. Louis, MO can accommodate generator field rewinds of any capacity, including large 4-pole nuclear units. Our generator experts can also perform a stator rewind on-site. We aslo have a Generator Field Swap Out Program with fields available to support forced or emergent outage needs.
Through years of power generation industry experience, our generator repair specialists conduct full-scope electrical testing, visual inspections, and specialty tests as per customer requirements.
Our generator in-situ inspection robot, MD&A’s Air Gap-Bot, can perform full generator inspections without removing the field, saving time and money on the outage.
We invest heavily in the development of people, procedures, and principle which facilitate improvements in design, reliability, and performance. Our generator experts designed many solutions to numerous aging fleet issues; for example, 7FH2 generator spring migration repair and dusting on 7FH2 & 324 stator end winding systems.
MD&A performs in-place stationary shaft machining, which enables repair of damaged journals, collector rings, and seal areas without removing turbine and generator rotors from the unit. Repairs are completed while stationary or on turning gear.
Our MD&A patented Two-Piece Clip addresses all known leakage and porosity issues with water-cooled stators.
MD&A’s experienced generator team can remove and install flexible leads in GE® generators.
MD&A Turbine and Generator Controls Division has a strategic partnership with Lectrodryer® to perform installation and commissioning services for their Generator Automated Hydrogen Purge Package.
